Michael, List, That passage is quite a gem. Having said that, I find the discussion difficult to make out. What might we do to arrive at greater clarity about what the distinction between the conceptions of a perfect and an imperfect continuum consists in and what the basis of the distinction rests on?

In going over the proofs of this paper, written nearly a year ago [1907], I can announce that I have, in the interval, taken a considerable stride toward the solution of the question of continuity, having at length clearly and minutely analyzed my own conception of a perfect continuum as well as that of an imperfect continuum, that is, a continuum having topical singularities, or places of lower dimensionality where it is interrupted or divides… . If in an otherwise unoccupied continuum a figure of lower dimensionality be constructed __ such as an oval line on a spheroidal or anchor ring surface __ either that figure is a part of the continuum or it is not. If it is, it is a topical singularity, and according to my concept of continuity, is a breach of continuity. If it is not, it constitutes no objection to my view that all the parts of a perfect continuum have the same dimensionality as the whole. (Strictly, all the material, or actual parts, but I cannot now take the space that minute accuracy would require, which would be many pages.) That being the case, my notion of the essential character of a perfect continuum is the absolute generality with which two rules hold good, first, that every part has parts; and second, that every sufficiently small part has the same mode of immediate connection with others as every other has. (CP 4.642) With that, I will rest my case.

After some irrelevancy re the Continuum Hypothesis, you make some statements about continuity and the philosophy of the natural sciences, continuity and chemistry, and “continuity in term of units, individuals and collections” -- three sets of comments about continuity, none involving the continuum. Where’s the purported distinction between continuity and the continuum – i.e., between the continuity exhibited in continua and any other alleged continuity? Where are CSP’s words that indicate such a distinction? What has this claim – “One notion of continuity was constructed by CSP from units, individuals and collections” -- contrasted with this claim – “A second notion of usage of continuity emerges from Cantor's view of the number line as a closed interval that could be separated into two notions of distance” – got to do with a purported distinction PEIRCE makes between continuity and the continuum, other than that the former is exhibited in, and only in, continua? And how do these meandering musings confirm that “Kirsti’s intuition was spot on”? Nothing you say even begins to addresses this. I cited the late articles and passages where, to the contrary, CPS, as even Kirsti has now acknowledged, moves seamlessly between the two, in just the manner I have described. You have splashed a bunch of disconnected comments around, but have cited nothing in Peirce to the contrary. I don’t see the point of continuing this thread if you’re just going to toss a hodge-podge of unrelated statements around. And with this post, I will therefore close end my responses to these aimless meanderings.

So I don’t see the relevance.. The immediate relevance of my post is that this is a listserve for CSP writings and the recent correspondence relate to his writings, although I do not think that is what was of concern to you. Your post leave me puzzled about your penultimate post which in turn was puzzling, so I reviewed the tread from its beginning and read more widely. The immediate motivations for my contributions and, as I understand it, yours also, was the issue raised by Kirsti with respect to the possible distinction the continuum and continuity in philosophy, mathematics and CSP's writings. Your post (Nov 12) expresses this perspective: Continuity is simply the unique quality which continua, and only continua, exhibit. Does this assertion close the philosophical issue that Kirsti raised? In response to John Deely's questions (post 18 in the listing) "Deely, John N." [[email protected]<mailto:[email protected]>] kirjoitti: Kirsti, would you mind clarifying for me, if possible (but not necessarily) with some specific ref. to a Peirce text(s), your remark re the difference between "continuity" and "continuum": I believe that it is relevant to cite the specific texts 4.172-176 from CSP in part of the answer to John's and Kristi's questions. These paragraphs brought to mind the Cantor's famous "Continuum Hypothesis" . A couple of citation from the web place the concept of the Continuum is a completely different context that that of mere continuity. [Introduction. Arguably the most famous formally unsolvable problem of mathematics is Hilbert's first problem: Cantor's Continuum Hypothesis: {The proposal originally made by Georg Cantor that there is no infinite set with a cardinal number<http://mathworld.wolfram.com/CardinalNumber.html> between that of the "small" infinite set of integers<http://mathworld.wolfram.com/Integer.html> [aleph_0] and the "large" infinite set of real numbers<http://mathworld.wolfram.com/RealNumber.html> (the "continuum<http://mathworld.wolfram.com/Continuum.html>"). Symbolically, the continuum hypothesis is that [aleph_1=c] . Problem 1a of Hilbert's problems<http://mathworld.wolfram.com/HilbertsProblems.html> asks if the continuum hypothesis is true.] Another aspect of this issue was how did CSP relate his views on continuity to the philosophy of the natural sciences? And these to synechism? 4.584 (1906) It is that synthesis of tychism and of pragmatism for which I long ago proposed the name, Synechism Yet, with respect to chemistry and continuity, he writes CP1.62 (1896?) Now it enters into every fundamental and exact law of physics or of psychics that is known. The few laws of chemistry which do not involve continuity seem for the most part to be very roughly true. It seems not unlikely that if the veritable laws were known continuity would be found to be involved in them… This is to be contrasted with his statements in 4. 173 where he justifies the origin of continuity in term of units, individuals and collections, strongly implies a consistency with the legisigns of chemistry with atoms as units, individuals as proper names of elements and collections becoming continuous. Thus, my conclusion from these readings is that Kristi's intuition was spot on. One notion of continuity was constructed by CSP from units, individuals and collections. A second notion of usage of continuity emerges from Cantor's view of the number line as a closed interval that could be separated into two notions of distance, as shown in his well know "removal of the middle third" argument to construct infinite numbers of continuous closed intervals from a line of UNIT length. The "Continuum Hypothesis" is a proposition about Cantor's mathematical philosophy. It is not an extension of CSP's notion of continuity. On another topic, I think it is important to support Stefan's quote of CP 5.131: "Man makes the word, and the word means nothing which the man has not made it mean, and that only to some man. But since man can think only by means of words or other external symbols, these might turn round and say: ”You mean nothing which we have not taught you, and then only so far as you address some word as the interpretant of your thought.“ In fact, therefore, men and words reciprocally educate each other; each increase of a man‘s information involves and is involved by, a corresponding increase of a word’s information." I was not aware of this quote, but have had a similar thought in mind for decades from my sensory experiences in the world. The observation that meaning is individualized is true for all individuals as a consequence of their antecedent sensory experiences. It is also true of language usage among disciplines. It is particularly important for those who love knowledge.

Deely; Määttänen Kirsti Subject: Re: [PEIRCE-L] Continuity, Generality, Infinity, Law, Synechism, etc. List, Michael, Kirsti, John: On Nov 12, 2014, at 11:47 AM, Michael DeLaurentis wrote: I don’t find any such distinction, implicit or explicit, in Peirce’s late writings. Motivated by your assertions, I re-read 4.172 and later paragraphs, searching for distinctions between CSP logic and set theory logic. In contrast to your assertion, I certainly find numerous critical philosophic distinctions between CSP logic and Cantorian/Russellian logic with respect to inquiry into the mathematics/logic of the continuum. Although a large number of texts could be cited, availability of time and energy restrict my rhetoric principally to 4.172 to 4.176. 1. 4.173 introduces with the notion of a collection. A collection is a consequence of "bring or gather together", parts of a whole. CSP bases his notion of relation on collections as parts of a whole. It requires activity to bring together a collection. Thus, CSP is grounding his argument, among other mathematical concepts, on the theory of numbers, the collectability of numbers, and the antecedent parts being brought together to construct a whole. This is clearly distinct from Cantor / Russell views which pre-supposes a geometric line. 2. 4.174 (and 4.172) introduces the notion of a relative of a part versus the relative of a whole, drawing on the statistical example in 4.172 and the concept of a unit of a partition of a role of a pair of dice. Each role of the pair of die generates a relative value among all possible roles of the pair of six-sided die, exactly 36. This is clearly distinct from Cantor / Russell views. 3. 4.175 "But when the units lose there individual identity because the collection exceeds every positive existence of the universe, the word multitude ceases to be applicable. I will take the word multiplicity to mean the greatness of any collection discrete or continuous." I infer from this, in light of 4.172-175, that individual identity is related to parts of a whole such that parts, as units, can be collected into whole, generating the NOUN, collection. The "bringing together" of a collection is of the nature of a sublation. The quality of the collection, is, presumable for CSP, a matter of sensory experience, as one perceives from the usage of the term "because" in this sentence, inferring causality. (And qualities are an aspect of sensory experiences, are they not?) This is clearly distinct from Cantor / Russell views of memberships and classes. Yes, set theory, as a dominant force in modern mathematics, has ignored the logical basis of CSP notion of multitude and his terminology for distinguishing between parts and wholes, points and lines, and sensory experiences. But, CSP’s philosophy expressed in 4.172-4.175 is consistent with many aspects of chemical logic; modern mathematics is not consistent with chemical logic for very specific reasons of the non-transitivity of the mathematics of chemical sublations of individual identities. Non-transitivity is illustrated, for example, by the handedness of chemical isomers.) I conclude that although many many aspects of CSP logic and set theory logic are consistent with one another, the distinction between them (modes of constructions) at the rhetorical and semantic levels differ in mathematically profound ways. The basic conundrum of the nature of distinction between discrete and continuous mathematics remains alive and open. Indeed, a very active subfield of mathematics is the Brouwer School of intuitionism. ( http://en.wikipedia.org/wiki/Intuitionistic_logic ) Parenthetically (or perhaps metaphorically) I conclude that studying CSP texts without an in-depth knowledge of the state of the science in the 2nd half of the 19 Th Century is like attempting to solve a crossword puzzle with only the superficial "across" clues. The depth of his thought corresponds with knowledge of mathematics and the natural sciences and the natural propositions in his time, that is, the "down" clues. Extending the metaphor, the sensory experiences of the American cultural milieu of the late 19 Th Century are interwoven into the very fabric of CSP's text.
